Python AppNotification

This sample uses Windows App SDK AppNotificationBuilder and AppNotificationManager to build and display a notification from an unpackaged Python process. It demonstrates:

• Windows App SDK bootstrap;
• a fluent generated builder API;
• an activation event delivered to Python; and
• asynchronous cleanup of the notification.

Unlike PyWinRT's toast activation sample, this version uses the Windows App SDK registration API and does not require a custom comtypes local server or manual registry keys.

Prerequisites

• WinApp CLI 0.6.2 or newer;
• dynwinrt installed in the selected Python interpreter; and
• dynwinrt-codegen on PATH, or passed with -Codegen.

Run

winapp restore
.\generate.ps1 -Codegen ..\..\..\target\release\dynwinrt-codegen.exe

.\run.ps1 -Python C:\path\to\python.exe -Major 2 -Minor 3

winapp restore prepares the pinned SDK metadata and bootstrap binaries under .winapp\. generate.ps1 uses that metadata to generate Python bindings and copies the selected architecture's bootstrap DLL to .runtime\.

Major and Minor default to 2 and 3. They must exactly match the Windows App SDK product version represented by the metadata, bootstrap DLL, and installed runtime.

The sample subscribes before registration, displays the notification, waits for activation, removes the notification, and clears all sample registration data before exiting. Registration cleanup still runs if notification removal fails.

Use -Smoke to validate support and build the notification payload without registering or displaying it.
